Design and methods for a community-based intervention to reduce sugar-sweetened beverage consumption among youth: H2GO! study

Article metrics

Abstract

Background

Reducing sugar-sweetened beverage (SSB) intake is an important dietary target among underserved children at high risk for obesity and associated morbidities. Community-based approaches to reduce SSB intake are needed. The use of narrative-based approaches (presenting messages within the context of a story) can facilitate connection with target health messages and empower children as behavior change agents within their families. The H2GO! program is a community-based behavioral intervention that integrates narrative-based strategies to reduce SSB consumption and promote water intake among school-age youth and parents.

Methods

Guided by the Social Cognitive Theory and the Social Ecological Model, the H2GO! intervention consists of 6 weekly sessions that target beverage knowledge, attitudes, and behaviors through youth-produced messages and narratives to reduce SSB intake and encourage water intake and parent–child activities. To reach underserved youth and families, we identified Boys & Girls Clubs (B&GC) (youth-based community centers that serve an ethnically diverse and predominantly low socioeconomic status population) as a community partner and study setting. Participants (children ages 9–12 years and their parents) will be recruited from B&GC sites in Massachusetts, USA. Intervention efficacy will be assessed through a site-randomized trial (N = 2 youth-based community sites, pair-matched for size and racial/ethnic composition) with 54 parent–child pairs (N = 108) enrolled per site (N = 216 total). The comparison site will carry on with usual practice. Child and parental SSB and water consumption (primary outcomes) and parent and child beverage knowledge and attitudes (secondary outcomes) will be measured via self-report surveys. Additional outcomes include children’s anthropometric data, additional dietary behaviors, and physical activity. Measures will be collected at baseline, 2 and 6 months follow-up. With an estimated 20 % dropout rate, the study will have 80 % power to detect a group difference of 3.9 servings of SSBs per week.

Discussion

Community-based approaches hold potential for decreasing SSB consumption among youth and families, particularly among underserved populations who are at greater obesity risk. This article describes the design and methods of a community-based behavioral intervention designed to reduce SSB consumption among youth and parents/caregivers.

Background

Sugar-sweetened beverages (SSBs) are aggressively marketed to youth [1], comprise the leading source of added sugars to children’s diet [2], and provide little to no nutritional value [36]. Overall SSB intake has increased among U.S. youth over the past 10 years [7], averaging at 224 kcal/day (approximately 11 % of total caloric intake) [2]. Several studies have shown that high SSB intake is strongly linked with childhood obesity [2, 814]. Differences in children’s SSB intake parallel disparities in childhood obesity; higher rates of obesity and heavy SSB consumption (>500 kcals/day) are prevalent among low socioeconomic status (SES) children compared to high SES children, and among Latino and Black children compared to White children [8, 15, 16].

In contrast to excessive SSB consumption, research indicates that water intake among U.S. children and adolescents has been inadequate over the past decade [17, 18]. Data from the National Health and Nutrition Examination Survey (2009–2012) indicates that more than half (54.4 %) of youth ages 6–19 were not adequately hydrated (defined as urine osmolality ≥ 800 milliosmoles/kg), with nearly a quarter reporting consuming no plain water at all [18]. With over one third of U.S. children currently overweight or obese and at risk for numerous associated health risks, including having a shorter life expectancy than their parents [19], replacing SSBs with water is an important dietary behavior to target among children at elevated obesity risk.

As the majority of SSBs consumed by children take place at home [4, 8], approaches that address parental behaviors related to SSB and water intake (e.g., modeling, purchasing) are needed. Existing childhood obesity interventions that engage children and parents typically include children as passive recipients (e.g., receiving education from an expert) and utilize didactic approaches. These interventions have yielded modest effect estimates and lacked sustainability [20, 21]. Interventions that empower children as behavior change agents within their families have the potential to enhance child behavior change and parental engagement. The use of narrative-based approaches (presenting messages within the context of a story) may facilitate greater connection with target health messages compared to pure didactic instruction [22]. Examples of narrative-based approaches include integration of comic books, telenovelas, and live peer stories within interventions to reinforce targeted health behaviors. Narrative-based interventions have been associated with positive health behavior change among low SES, racial/ethnic minority adults [2224].

To reach underserved youth and families, we identified local Boys & Girls Clubs (B&GC) of America as a community partner and intervention setting. B&GCs provide affordable after-school programs for ethnically diverse and predominantly lower socioeconomic status populations through nearly 4000 sites across the U.S. [25]. Central to the B&GC mission is partnering with families to promote healthy behaviors. If shown effective, the intervention will eventually be integrated into existing B&GC health programs delivered by trained B&GC staff. No community-based childhood obesity intervention to our knowledge has empowered children as change agents to convey key health behavior messages to parents. The purpose of this manuscript is to describe the design and methods of a community-based behavioral intervention to target SSB and water intake among an ethnically diverse sample of youth and families.

Methods

Study aim and design

This study aims to assess the feasibility and efficacy of a community-based behavioral intervention (delivered through B&GC sites) targeting SSB and water consumption among 108 parent–child pairs (N = 216) through a site-randomized trial. The site-level intervention will take place at two B&GC sites that were pair-matched for size and racial/ethnic composition. One site will be randomized to receive the intervention and the other site will receive usual care. The 6-week intervention consists of weekly group-based sessions with assessments conducted at baseline, 2 and 6 months follow-up (see Fig. 1 for study design). The primary outcomes are child and parental SSB and water intake, assessed via validated survey items. Secondary outcomes include child and parental knowledge and attitudes related to SSBs. Additional outcomes include children’s anthropometrics (height, weight and waist circumference), other dietary behaviors, and physical activity. We hypothesize that child participants in the intervention site will demonstrate reduced SSB intake and increased water intake compared to participants in the comparison site at 2 and 6 months follow-up. Study protocol and procedures were approved by the Boston University Medical Center Institutional Review Board.

H2GO! Study Design

Study setting and population

The B&GC of America is a national organization that provides affordable after-school programs for a large population (~4 million annually) of diverse youth (33 % White, 30 % Black, 23 % Latino) from predominantly low socioeconomic backgrounds through over 4000 club facilities across the U.S. [25]. Given the organization’s commitment to health promotion through health programs delivered by professionals trained in youth development, B&GCs serve as an ideal setting to deliver childhood obesity programs that target ethnically diverse and low SES populations. Given the wide local, state, and national reach of B&GCs to underserved youth, an efficacious behavioral intervention targeting SSB and water intake has high potential for sustainability and dissemination. Two B&GC sites (Worcester and Lowell) in Massachusetts, USA were selected for comparability in youth enrollment size and racial/ethnic composition and geographic spacing (>40 miles apart) to reduce contamination. See Table 1 for participating B&GC site characteristics.

Table 1 Characteristics of Boys and Girls Club study sites (2012–2013) in Massachusetts, USA

Parent–child pairs will be recruited from B&GC sites. Child inclusion criteria are: ages 9–12 years; current member at the B&GC study site; able to understand and communicate in English, able and willing to provide consent; parental/caregiver permission to participate; and no medical condition that limits ability to change beverage consumption behaviors. Parental/caregiver inclusion criteria are: parent/caregiver to a B&GC child member; 18 years or older; able to understand and communicate in English; able and willing to provide consent; and no medical condition that limits ability to change beverage consumption behaviors.

Intervention condition

Development

The intervention was designed to address two behavioral targets: reducing the number of SSB servings consumed per day (recommended guideline of zero SSBs per day) and promoting water consumption (approximately 5–8 cups per day for youth participants and eight cups per day for parental participants). Intervention materials, strategies, format, and content were pilot-tested among a small sample (N = 12) of parent–child pairs at a B&GC study pilot site (Lawrence, MA) and finalized based on feedback from parent and child participants, B&GC staff, and observations from the research team. Informed by the Social Cognitive Theory [26] and the Social Ecological Model, the H2GO! Intervention was designed to target child and parent participants’ knowledge, attitudes (self-efficacy, outcome expectations, perceived social norms) and behavioral capabilities [27] related to SSB and water consumption.

Intervention format, content, and strategies

The 6-week intervention consists of group-based weekly sessions (1-h sessions twice a week) delivered by trained B&GC program staff at the B&GC site. Each intervention session consists of a 1-h health module followed by a 1-h narrative module. Topics of the health modules include: understanding the benefits of water, sampling different types of fruit-flavored water, identifying SSBs, exploring the local grocery store, identifying barriers and facilitators to drinking water, and managing triggers for SSBs. See Table 2 for content and objectives targeted during each session. The narrative modules include intervention objectives and activities that reinforce knowledge, attitudes, skills, and behaviors targeted in the previous health component (e.g., if the health topic covers how to identify SSBs, the narrative module guides youth in creating their own messages and narratives through print, audio, or video materials that focus on how to identify SSBs).

Table 2 H2GO! intervention content

Child participants will receive a reusable water bottle and a pictorial intervention booklet. Developed by the study principal investigator (PI) and research assistants, the brightly-colored 45-page booklet was culturally and linguistically-tailored to the study population and included intervention activity worksheets, parent–child take-home activities, fun facts and quizzes, and water and SSB consumption tracking sheets. Activity worksheets will be completed by participants during intervention sessions; and parent–child take-home activities will be completed following each session. Figure 2 presents sample intervention strategies utilized at the individual, interpersonal, and social and physical environmental levels, and Table 3 presents intervention strategies and activities used to target constructs of interest.

Comparison condition

Participants in the comparison site will receive usual care at the B&GC (standard programming) during the study and complete assessments at baseline, 2 and 6 months follow up. The comparison B&GC site will receive an intervention toolkit including intervention materials, protocols, and supplies upon study completion.

Intervention fidelity

Several strategies will be utilized to maximize intervention fidelity. Prior to study start, the research team will provide in-depth training sessions on all intervention materials and study procedures for B&GC health program staff. The training consists of a comprehensive intervention protocol review, didactic and discussion-based sessions, and mock sessions with feedback provided by research staff. Intervention delivery will be supervised by the PI and 1–2 trained research assistants. Research team members will attend and complete intervention fidelity checks during each intervention session to assess the extent to which intervention activities were completed as designed. Intervention fidelity checks consist of a list of protocol activities for which the extent of fidelity was rated on a scale of 0 to 2 (0 = did not do this activity; 1 = partially completed; 2 = completed), space for comments regarding each activity, and duration of intervention session.

Participant recruitment

Screening and recruitment will be conducted by the study team (PI, research coordinator) and B&GC staff. The PI will train the research coordinator and B&GC staff in implementing the screening and recruitment protocols and oversee the screening and recruitment process through weekly in-person meetings. In collaboration with B&GC staff at each study site, the PI will design a fact sheet to introduce the study to potential child and parent/caregiver participants. Recruitment packets containing the fact sheet, study eligibility, consent forms, and study procedures will be provided to B&GC staff to distribute among youth within the eligible age range (9–12 years) and parents/caregivers of youth within this age group. B&GC staff will also verbally inform youth of the study, presenting it as a healthy habits program in order to avoid explicit announcement of the underlying hypotheses about SSB consumption and obesity risk.

After an initial pool of interested youth are identified, the research coordinator and B&GC staff will screen youth for eligibility (details provided in Study Setting and Population). The research coordinator will provide further explanation of the study, review study assent forms, and answer questions. The PI will also be available to answer questions and address concerns. Interested and eligible youth will be given study recruitment packets containing study information and consent forms for parents/caregivers. During pick-up time at the B&GC, the research coordinator will meet with parents/caregivers of interested and eligible youth participants, screen parents/caregivers for eligibility (details provided in Study Setting and Population), provide further explanation of the study, review study consent forms, and answer questions. All participants will be informed procedures to protect the confidentiality of data collected and that their care at the B&GC would be in no way affected by study participation. Interested and eligible parent–child pairs will be asked to complete three written consent forms (child assent to participate, parental consent for their child to participate, and parental consent to participate as a study participant). Only parent–child pairs who complete all three forms will be enrolled in the study. Enrolled child and parent/caregiver participants will be asked to complete baseline assessments prior to the intervention start date.

Study measures

Study assessments will be led by trained researchers and conducted at B&GC sites at baseline and two follow-up time points (2 and 6 months post-baseline).

Feasibility outcomes

The number of parent–child dyads available for recruitment and retention using a CONSORT diagram [28, 29] and the number and reasons for failure to complete follow-up assessments will be reported. To assess intervention engagement, B&GC staff in the intervention site will track child intervention session attendance rates, number of narrative materials completed per child, percent of parent–child take-home activities completed, and parent and child attendance rates of the family viewing celebration.

Immediately following intervention completion, parent and child participants will rate/report the following indicators on intervention satisfaction and acceptability: overall satisfaction with each intervention component (youth sessions, narrative materials, parent–child take-home activities, and Club open house event); likelihood of referring intervention to a friend; likelihood of participating in a similar intervention targeting a different dietary behavior; intervention aspects perceived to be most useful; and suggestions to improve the intervention. A 5-point Likert scale will be used to assess outcomes 1–4; open ended responses will be used to assess outcomes 5–6.

Efficacy outcomes

The primary outcomes, child and parent consumption of SSBs and water (frequency, type, and servings of SSBs and water consumed on a typical day in the past 7 days) will be assessed using items from the Youth Risk Behavior Surveillance Survey [30] and a validated youth food-frequency questionnaire (FFQ) [31]. Secondary outcomes (knowledge related to SBBs and water, self-efficacy to reduce SSB intake and drink water) will be assessed among children and parents using modified items from validated surveys [32, 33]. Child height, weight, and waist circumference will be measured at each assessment point using portable digital scales, stadiometers, and tape measures with the participant wearing light clothing and no shoes; measurements will be taken to 2/10th of the nearest inch or pound. Body mass index will be calculated as weight (kg)/height (m2). Youth Risk Behavior Surveillance Survey items [30] will be used to assess children’s other dietary behaviors, such as frequency of fruit, vegetable, breakfast, and fast food consumption and intake of non-SSBs (i.e., diet drinks, water, 100 % fruit juice), and children’s physical activity and sedentary behaviors (i.e., frequency and duration of moderate-to-vigorous physical activity and screen time activities). Covariates of interest will be assessed through self-report surveys and include child and parent gender, race/ethnicity, and age; child eligibility for free/reduced priced lunch; and parental education, income, and employment status.

Power calculation

Our sample size calculations are based on the primary hypothesis that child participants in the intervention site will have reduced SSB intake and increased water intake than child participants in the comparison site at 2 and 6 months follow-up. Results from our pilot data indicate that B&GC children consumed an average of 7.6 servings of SSBs over the past 7 days (SD = 6.5). Assuming that youth in the comparison site will experience no change in SSB intake from baseline to follow-up, a two-sided, two-sample t-test of means with alpha = 0.05 and 80 % power indicates that enrolling 45 children per group will allow us to detect a difference of 3.9 servings of SSBs per week, a clinically meaningful difference of approximately 550–940 kcals per week depending on serving size and SSB type. To account for 20 % dropout, we will enroll 54 parent–child pairs (N = 108) per site, yielding a total sample size of 216 participants.

Analysis plan for feasibility and efficacy outcomes

For feasibility outcomes, recruitment and retention rates will be compared across study sites and t-tests will be used to compare overall rates between the two sites. The number and reasons for failure to complete follow-up assessments will be reported. To analyze intervention engagement, youth session attendance rates for each session, percent of parent–child activities completed per week, number of narrative materials produced per child, and parent and child attendance rates at the club open house event will be reported. Intervention fidelity rates per session will be reported, and reasons for poor fidelity will be explored. For intervention acceptability and satisfaction, we will report descriptive statistics of intervention satisfaction ratings among children and parents and the proportions of children and parents who would recommend the intervention to others.

Distributions, descriptive statistics, and missing values will be examined for all efficacy study variables. Bivariate analyses will compare the characteristics of the intervention and comparison groups using two-tailed chi-square tests for categorical variables and two-tailed t-tests for continuous variables. These results will identify imbalances between groups that will be adjusted for in multivariable analyses. All analyses will utilize an intent-to-treat approach, with each child and parent participant enrolled in the intervention site analyzed as part of the group, regardless of intervention engagement. We will compare mean changes in our primary outcome (children’s SSB intake frequency) and secondary outcomes across intervention conditions using repeated measures mixed models. Generalized estimating equations will be used to account for clustering of observations within sites. Based on the relatively small sample size, complete case analysis with comparisons with baseline data will be used to address missing data as a result of loss to follow up.

Discussion

Community-based and narrative-based intervention strategies hold potential for decreasing SSB consumption and associated obesity risk among youth and families, particularly among socioeconomically disadvantaged and racial/ethnic minority populations who face disproportionately high obesity rates. Findings from this study will be used to assess efficacy on reducing SSB consumption among youth and families in the USA. If efficacious, the intervention has high potential for dissemination across youth-based settings and will serve as a community-based intervention model to target SSB and water consumption and disparities in childhood obesity.
